Design Source Solutions Inc., a Liberty Lake-based product development and manufacturing firm, expects to move this month into a newly upgraded space in the Meadowwood Technology Campus, also in Liberty Lake.

The company will occupy almost 5,200 square feet of space following about $50,000 in tenants improvements that started mid-December, says Wayne Frost, managing director for Greenstone Commercial, which is managing the property for the building's owner, Meadowwood Partners LLC.

Meadowwood Partners LLC is a subsidiary of Liberty Lake-based real estate developer Greenstone Corp., which owns the campus and the 250,000-square-foot main building. The Meadowwood Technology Campus currently has six tenant businesses, Frost says, and he anticipates there is room for seven or eight additional tenants.

Divcon Inc., of Spokane Valley, is completing the tenant improvements. Bernardo-Wills Architects PC, of Spokane, designed the space.

Design Source, which was founded in 2007, previously leased about 3,000 square feet of space at 1721 N. Madson, in Liberty Lake, in an office suite at the back of Premier Manufacturing Inc.'s building, says Scott Pennestri, Design Source's president.

He says the business moved to temporary Meadowwood quarters in December until the upgrades could be completed. He adds that the larger space is needed at least in part because of a large aerospace contract that the company recently landed. He declined to disclose the details of the contract.

Pennestri says the company employs seven workers, but it plans to hire five new employees during the current quarter. He adds that he expects an additional 10 workers will be hired before the end of 2012, for a total of 15 new employees this year.

Frost says the tenant improvements for Design Source include new walls, offices, a receptionist counter, conference room, painting, lighting, fixtures, and carpeting. The areas include about 3,300 square feet of space at the basement level for the company's manufacturing and assembly areas, and just over 1,800 square feet on the main floor for the company's headquarter offices.

Design Source works to assist clients during the design phase of a product, either taking on the entire design process or helping to complete those ideas that a company has already developed, Pennestri says. Its internal manufacturing capabilities include electromechanical assembly for products, he says, and the company also is building a focus on solenoid design and manufacturing, which is used in valves and control systems.

Some of its clients include companies in telecommunications and medical industries, and the military for hand-held devices, Pennestri adds.
